' My invention" relates to improvements in building construction, and more particularly, tothe advantageous support of metalli'c. structural members, such as I-beam's and the like, from the top flanges thereof; the object of my invention beingto afford acheap and efllcient means for erecting structural members of a building.

, My invention may be advantageously described in connection with the erection of structures employing socalled metallic lumber, comprising light channeled members which are united back to back by spot welding to approximate the cross section of an V though my improvements are not necessarily limited to the particular means set forth for explaining the same, nor as illustratively shown in the accompanying drawing, wherein:

Figure 1 is a view, partly in transverse section, of a girder, carrying the two opposed ends of metallic lumber members from their upper flanges by means of a simple angle-bar bracket construction in accordance with my invention.

Fig. 2 is a fragmentary plan view thereof, partially broken away, and in section.

Fig. 3 is a fragmentary section on line 33, Fig. 1, and

Fig. 4 is a perspective View, terminally sectioned, illustrating a supporting bracket member adapted for the improved building construction herein defined.

5'0- Throughout the several figures of the drawing I have employed'thesame character of reference to indicate similar parts. i The essentials of a building construction sufllcient to explain my invention are shown in the aforesaid drawing to typify the same and comprise a heavy I -beam or girder a, which may beassumed to be't ermina'lly sup ported by the building walls in the usual. manner. Laterally thereof there are shown the broken away ends I) of two lengths ofmetallic lumber comprising channel-members b b united along their webbed faces by spot welding, for example. Thus they constitute a fabricated I b'eam." Y

- Fig. 4 illustrates a preferred composite member for terminally supporting theme tallic lumber Z), b',or other flanged or I-beam structures from the top flanges thereof; This comprises the angle bars 0, 0, united by the bolts 03, at, and having the lugs 0" 0 stamped from their base 'portionsto format taching clips,"as bestshown in Fig.1. This supporting member may be of any si'iitable; length for extending beneath the upper flanges of "the joist members in order terminally to carry the superimposed weight. The angle. bars maybe tightened against the embraced webs by'fmeans'of the b'oltsand' nuts (Z, d," advantageously, but thejoi t 1nem-' bers primarily are supported by the verti+ c0 cally positioned. embracing lengths of the" angle barsc, 0, Thus, these I beam sections require no reinforcementand no preparation. by way of trimming or punching bolt holes, for example; hence. the building construction S5 described is extremely easy toerectandjis cheap and serviceable for the" relatively" lighter loadings. p v I am'aware' that I-beams previously have been erected by means of terminally embracing members clamped to the webs thereof by means ofbolts passing through and through. the respective thicknesses of metal form ing bracketed supports upon metallic posts? and the like; This construction, however; is dissimilar tothe embodiment. ofmy inven tion in that thestructurally unattacliedbutterminally supported I-beams are carried from their top flan s; and" the; supporting member bears directlyup on'theupper face of 1 t {the joist, thereby obviating theexpense for any labor in preparing and adapting the members for erection as a building unit.
